Thank you for your recent inquiry regarding this item from Prime-Line Products. Because this is a universal tee handle with various adapting inserts, one of them should work. However, since there is not one tee handle that is standard to all operators, there is no sure way to determine the correct replacement handle without removing one and matching its dimensions to those listed online. Window manufacturers can often use more than one design within a given series or product line used over the years, making it sometimes difficult to provide an exact match when relying on manufacturer name and series alone. If the spline diameter of your window matches one of the insert sizes, then this item should work just fine.
